Title: A device for the fine adjustment of bearing clearance in shaft bearings
IPC: F16C25/02
Filed: 1956-02-03
Abstract: 779,331. Adjusting bearings. AKT.-GES., F. STUDER. Feb. 3, 1956 [Feb. 5, 1955], No. 3484/56. Class 12 (1). Adjustment of the clearance between a shaft 2 and bearing 13 is effected by rotation of a nut 15 which is screwed on to the end of the bearing 13 and is located axially between a housing 12 and cover 18 secured thereto. Adjustment of the nut 15 causes axial movement of the bearing 13 and consequential variation of the clearance between the co-operating conical surfaces of the bearing and shaft. Axial movement of the shaft is prevented by spacer sleeves 8, 9 located between adjustable ring nuts 5, 6 on the shaft and thrust surfaces 10, 11 respectively on the housing. In a modification, the shaft has a cylindrical journal surface which co-operates with a bearing bush 23 having a cylindrical bore and a conical outer surface. A housing sleeve 26 has a correspondingly tapered bore. The bearing bush 23 is rendered resilient by longitudinal slots 24, 25, and a twopart spreader wedge 27, operated by screws 28, is provided to expand the bearing bush 23. The adjustment may be carried out whilst the spindle is rotating.

IPC: C21C5/46
Filed: 1969-01-22
Abstract: 1,235,657. Oxygen lances. SOC. LORRAINE DE LAMINAGE CONTINU. 22 Jan., 1969 [25 Jan., 1968], No. 3683/69. Heading F4B. An oxygen lance for use in a Kaldo-type furnace, comprises a main duct 4, a plurality of auxiliary ducts 12 and a cooling circuit, to said main duct having a rearward section 4b which is connected to a source of oxygen, a forward section 4a which has an outlet orifice 6 and is of a length which is at least four times its mean diameter, and a mixing chamber 15 interconnecting said rearward and forward sections, the said auxiliary duct 12 being disposed externally of the rearward section 4b and debouching substantially tangentially into the mixing chamber 15. The auxiliary ducts 12 are defined by grooves 13 of a screwthreaded sleeve 14 and by the internal wall of a connecting sleeve 10. In operation, the secondary source of oxygen 9 causes the rotation of all the oxygen passing through the main duct 4, the total quantity of oxygen issuing from the mixing chamber undergoing, in the section 4a, a sufficient pressure loss so that at the orifice 6 the jet of oxygen flares rapidly in the form of a cone.

The red filter element may also be selected so that its transmission range is between 350 and 390 mÁ, by colouring with rhodamine, Prussian blue and nitrosodimethylaniline hydrochloride. A correcting filter may be used in copying. Specifications 408,991 and 409,270 are referred to. The Specification as open to inspection under Sect. 91 refers to Specification 369,616 and comprises also the use of correction filters for exposure.

Title: Process and installation for the continuous casting of materials of high melting point, such as steel
IPC: B22D41/13
Filed: 1950-02-14
Abstract: 677,023. Foundry plant; continuous casting-machines. JUNGHANS, S. Feb. 14, 1950 [Nov. 22, 1948], No. 3789/50. Class 83 (i). [Also in Group II] In the continuous casting of highmelting-point materials, e.g. steel, the molten material is delivered to the mould in regular predetermined quantities, e.g. by a series of ladles which are successively filled, conveyed to the mould, discharged, cleaned, repaired or replaced, and refilled in a circuit, which may be circular, continuously. Each ladle 19, Fig. 3, may be centred in a metal vessel 16 lined with insulating material 18 by blocks 20 so that its opening 19a is in line with a nozzle 10, removably secured by a rotary annulus 28. The opening 19a is normally closed by a detachable plug 23 supported by an arm 30 and operated by known mechanism, not shown. The vessels 16 are each suspended by a yoke 7, Fig. 1, from a pulley 5 adjustably carried by a trolley movable on a circular track 1. At station I, after removing a cover 22, the crucible is charged with molten steel from a furnace 2, at II a nozzle, preheated in a furnace 11 is fitted, at III the vessel 6 is lowered and the molten steel is discharged into the mould 12. The vessel is then raised and at IV the nozzle 10 is detached and returned to the furnace 11 for repair or replacement and preheating and the plug 23 similarly to furnace 15. At V the vessel is cleaned by a burner 13, at VI it is detached from the yoke 7, heated in a furnace 14 in inverted position and re-attached and at VII the pre-heated plug 23 is refitted ready for another cycle. Electric or other heating means may be arranged between the ladle 19 and lining 18. In a modification and during the discharge of one ladle, the next may be lowered into position on the mould so that its discharge may start directly the other is empty. In order that the two nozzles may be brought close together each may be arranged eccentrically in the bottom of its vessel 16.

[Class 38 (ii)] [Also in Group XXXVII] Relates to on-load transformer tap changing arrangements of the kind described in Specification 500,763, and consists in arranging the conductors connecting the arcing contactor across the fixed contacts of the selector switch to form a circuit of low impedance so as to reduce sparking at the selector switch to a minimum and thus enable that switch to be accommodated in the transformer tank without risk of damage to the transformer oil. The transformer 1, ratio adjuster 8, interlinked chokes 90 and cam-operated selector switch 11 are disposed in a common tank on the wall 26 of which is mounted an auxiliary oil-tank 25 housing the cam-operated arcing contactor 22. The contacts 27, 28 of the latter are connected across the contacts 13, 14 of the selector switch by conductors which comprise a bolt 54 and a concentric tube 58 passing through the wall of the tank 26 and forming a low impedance circuit. The bolt 54 and tube 58 are carried by a pair of insulating bushings 45, 46 secured to opposite sides of the tank wall and carrying metal end plates 47, 48, and insulated metal caps 51, 52 which form connecting elements between the switch contacts and the bolt and tube. The ratio adjuster 8 and the cams 19, 40 operating the selector switch and arcing contactor are actuated by a common shaft 75 which may be driven by a capacitor motor 76 controlled by a contactmaking voltmeter 91 connected across the load circuit 5, 6.

Title: Improvements in or relating to means for determining courses and/or distances from a chart
Filed: 1934-02-07
Abstract: 414,308. Course indicators &c. BUNSTON, J., 37, Barrowgate Road, Chiswick, London. Feb. 7, 1934, No. 4078. [Class 97 (ii).] For determining great circle courses on a chart drawn on the mercator projection, a sheet movable relatively to the chart is marked with a series of arcs representing great circles of the Earth to the same scale and projection as the chart. As shown a transparent sheet 11, placed with its upper edge coincident with the equator on a chart 10, is marked with arcs 12 representing a series of great circles passing through points 13, 14 corresponding to the ends of an equatorial diameter of the earth. In use the sheet 11 is moved transversely, keeping its upper edge over the equator on the chart, until one of the great circles 12 passes through the two desired points, say A, B. The compass bearing of the course at any point may then be determined from the direction of the tangent at that point. A series of curves 15 representing on the mercator projection a series of circles about the points 13, 14 may be marked on the sheet 11 and used to indicate the distance between any two points on a great circle course. The sheet 11 may, in a modification be formed as an opaque table over which transparent charts are moved.

Filed: 1962-02-05
Abstract: The initial response time of a radiation detector employing a CdS crystal is decreased by exposing the crystal to a continuous background of green-blue light from ZnS : Ag energized by radio-active material.  The CdS crystal 10 is mounted in a sealed housing 15 with or without a transparent window depending on the type of radiation to be detected.  As shown in Fig. 2, the luminescent material 17 may be adjacent the crystal and be coated with a layer 18 of <PICT:0997183/C4-C5/1> radio-active material.  Preferably, however, the luminescent and radio-active materials are finely divided and mixed with polystyrene in a suitable solvent so that they may be applied with a brush as a single layer.  Instead of coating the CdS crystal, the luminescent and radio-active material may be coated on the inner wall of the housing 15.  Suitable radio-active materials are said to be radium salts, krypton 85, strontium 90, and tritium, the latter two being preferred as they do not emit g -rays.
